Background:
Mechanical bowel preparation (MBP) has been shown to have no influence on the incidence of anastomotic leakage in overall colorectal surgery. The role of MBP in elective surgery in combination with an inflammatory component such as diverticulitis is yet unclear. This study evaluates the effects of MBP on anastomotic leakage and other septic complications in 190 patients who underwent elective surgery for colonic diverticulitis.
Methods:
A subgroup analysis was performed in a prior multicenter (13 hospitals) randomized trial comparing clinical outcome of MBP versus no MBP in elective colorectal surgery. Primary endpoint was the occurrence of anastomotic leakage in patients operated on for diverticulitis, and secondary endpoints were septic complications and mortality.
Results:
Out of a total of 1,354 patients, 190 underwent elective colorectal surgery (resection with primary anastomosis) for (recurrent or stenotic) diverticulitis. One hundred and three patients underwent MBP prior to surgery and 87 did not. Anastomotic leakage occurred in 7.8 % of patients treated with MBP and in 5.7 % of patients not treated with MBP (p = 0.79). There were no significant differences between the groups in septic complications and mortality.
Conclusion:
Mechanical bowel preparation has no influence on the incidence of anastomotic leakage, or other septic complications, and may be safely omitted in case of elective colorectal surgery for diverticulitis.
Insights
Mechanical bowel preparation (MBP) does not impact anastomotic leakage or septic complications in elective colorectal surgery for diverticulitis. Omitting MBP is safe and recommended for these patients.
Area of Science:
- Colorectal Surgery
- Surgical Gastroenterology
- Diverticulitis Management
Background:
- Mechanical bowel preparation (MBP) effectiveness is debated in specific colorectal surgeries.
- Its role in elective surgery for diverticulitis remains unclear.
- This study addresses MBP's impact on anastomotic leakage and septic complications in diverticulitis patients.
Purpose of the Study:
- To evaluate the effect of mechanical bowel preparation (MBP) on anastomotic leakage.
- To assess MBP's influence on other septic complications and mortality in elective colorectal surgery for diverticulitis.
Main Methods:
- Subgroup analysis from a multicenter randomized trial.
- Comparison of clinical outcomes between MBP and no MBP groups.
- Focus on patients undergoing elective surgery for colonic diverticulitis.
Main Results:
- 190 patients with diverticulitis included; 103 received MBP, 87 did not.
- Anastomotic leakage rates were 7.8% with MBP vs. 5.7% without (p=0.79).
- No significant differences in septic complications or mortality were observed between groups.
Conclusions:
- Mechanical bowel preparation (MBP) does not influence anastomotic leakage rates.
- MBP has no impact on other septic complications or mortality in this patient group.
- MBP can be safely omitted in elective colorectal surgery for diverticulitis.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
